Hot spots are unusually hot places in the mantle where the magma plumes upward in a tube-like fashion. As the tectonic plate moves, the new crust created builds up and creates island volcanoes. The Hawaiian Islands are a hot spot. Hot Spots - The Hawaiian Islands Hot Spot Animation
Island arcs form at subduction zones and hot spots. Examples at subduction zone are the Japanese Islands and Aleutian Islands of Alaska. The Hawaiian Islands are a hot spot island arc. Island Arcs Animation Island Arc Formation

Magma
Magma is liquid or partially molten rock beneath the Earth's surface. When magma erupts onto the surface, it is called lava . Magma typically consists of (1) a liquid portion (often referred to as the melt); (2) a solid portion made of minerals that crystallized directly from the melt; (3) solid rocks incorporated into the magma from along the tube or reservoir, called xenoliths or inclusions; and (4) dissolved gases.

Lava
Lava is the word for magma (molten rock) when it erupts onto the Earth's surface. Geologists also use the word to describe the solidified deposits of lava flows and fragments hurled into the air by explosive eruptions (for example, lava bombs or blocks). Lava is from the Italian word for stream, which is derived from the verb lavare--to wash.
